State-of-the art teaching material of the OWASP Top 10
Nowadays, web security has become something indispensable when working with the Internet, whether to protect business databases, establish communications, etc. With the aim of creating teaching material, I have created some laboratory sessions and documented several issues related to the ?OWASP (Open Web Application Security Project) top 10 vulnerabilities?. As a method, a systematic review o information in a large number of reliable Internet resources has been carried out, and several laboratory exercises has been created. As a result a large amount of teaching material including some exercises has been created about different themes, mianly: JWT (JSON Web Tokens), JKUs (JWK Set URL) and JWKs (JSON Web Keys); Cookies, XSS Attacks (Cross Site Scripting). As a conclusion, this project collects information about different topics related to web security, and the exploitation of some vulnerabilities. With all this material, students can get a solid base on this topics and see the performance of some of this attacks.En la actualidad, la seguridad web se ha convertido en algo indispensable a la hora de trabajar con Internet, ya sea para proteger bases de datos empresariales, establecer comunicaciones, etc. Con el objetivo de crear material docente, he creado algunas sesiones de laboratorio y documentado varios problemas relacionados con el 'Top 10 de vulnerabilidades de OWASP'.

Effects of Whole-Grain and Sugar Content in Infant Cereals on Gut Microbiota at Weaning: A Randomized Trial
The introduction of complementary foods during infancy marks an important step in the
development of the infant gut microbiome. Infant cereals are popular weaning foods but consistent
evidence on their effect on the intestinal microbiota, especially when differing in nutritional quality,
is lacking. Fecal samples from 4–7-month-old Spanish infants who consumed infant cereals differing
in whole grain and sugar content as first weaning foods were analyzed on changes in microbial
composition by massively parallel sequencing of the 16S ribosomal RNA gene at baseline and
after 7 weeks of intervention. Samples were obtained from a previous trial conducted in Spain
demonstrating whole-grain cereal acceptability. In total, samples of 18 infants consuming 0% whole
grain cereals with 24 g sugar (0-WG) and 25 infants consuming 50% whole grain cereals with 12 g
sugar (50-WG) were analyzed. Microbial composition changed significantly over time (p = 0.001), per
intervention group (p = 0.029) and per infant (p = 0.001). Abundance of genus Veillonella increased in
both groups while Enterococcus decreased. Within the 0-WG group, phylum Actinobacteria decreased
along with genus Bifidobacterium. In the 50-WG, we observed an increase in Lachnoclostridium and
Bacteroides. In addition, 50-WG decreased Proteobacteria and Escherichia to levels lower than 0-WG.
Although weaning itself appeared to be responsible for most changes, the increased presence of
anaerobic fermenters together with inhibition of pathogenic Escherichia may indicate a supporting
effect of infant cereals with 50% whole grains and a reduced sugar content over infant cereals
manufactured with refined hydrolyzed flours on the infant microbiota. In fact, using a novel
methodology for the identification of microbial signatures, we found two groups of microbial taxa
predictive of infants consuming enriched whole-grain infant cereals with a high predictive value of
about 93%.European funding from ICEX and FEDER—Program

¿Diversidad cultural o desigualdad social? Una aproximación crítica a la competencia cultural en la salud a partir de las necesidades sentidas por mujeres en contextos de diversidad, injusticia social y austeridad
En el presente trabajo, se realiza un análisis crítico de la competencia cultural como estrategia para reducir las desigualdades en salud en contextos de diversidad asociada a la inmigración. Tras un breve recorrido histórico sobre el surgimiento y evolución de este concepto, se plantea una severa crítica a las políticas y prácticas de promoción de la competencia cultural dada su incapacidad para transformar las condiciones generadoras de desigualdad en el acceso a la salud y los servicios sanitarios en contextos de diversidad, particularmente en tiempos de crisis y austeridad.Neste trabalho, apresenta-se uma análise crítica da competência cultural como estratégia para reduzir as desigualdades em saúde em contextos de diversidade associada à imigração. Após um breve percurso histórico pelo surgimento e evolução deste conceito, faz-se uma severa crítica das políticas e práticas de promoção da competência cultural, dada a sua incapacidade para transformar as condições que levam à desigualdade na saúde e no acesso aos serviços de saúde em contextos de diversidade, particularmente nos atuais tempos de crise e austeridade.The main aim of this paper is to critically examine the adequacy of cultural competence as a strategy to reduce health inequalities in contexts of migration-driven diversity. After a brief historical overview of the emergence and evolution of this concept, cultural competence policies and practices are severely criticized due to their inability to transform the conditions leading to inequalities in health and healthcare in contexts of diversity, particularly in current times of crisis and austerity
La aproximación multimétodo en evaluación de necesidades
La evaluación de necesidades es una modalidad de investigación social aplicada,
de carácter evaluativo, que consiste en identificar y priorizar los problemas existentes en
un contexto determinado, como base para la planificación de intervenciones que incidan
sobre las principales carencias detectadas. A pesar de la amplia variedad de métodos de
investigación disponibles para el desarrollo de este tipo de estudios, la práctica de la
evaluación de necesidades suele caracterizarse por cierta pobreza metodológica, con un
claro predominio de la encuesta como principal o único método de recogida de información.
En el presente trabajo, tras realizar una breve revisión de las aproximaciones
metodológicas alternativas que es posible adoptar en el ámbito general de la investigación
social y la evaluación de programas, se propone un modelo multimétodo de evaluación
de necesidades que plantea el uso combinado de técnicas de investigación tanto cuantitativas
como cualitativas.Needs assessment is a type of applied social evaluative research, focused on the
identification and prioritization of problems in a specific context, as a base for intervention
planning oriented to solve the main identified needs. In spite of the huge availability of
research methods for the development of this kind of studies, needs assessment practice
is too often charaterized by certain methodological poverty, with a clear dominance of
the survey as the main or only research method. In the present paper, after a brief revision
of the methodological approaches that may be adopted in the general field of social
research and programme evaluation, a multimethod needs assessment model is proposed,
suggesting the combined use of both qualitative and quantitative research techniques
